Again mate, for whiteness and white supremacy to work in my favor, white society has to value me and my positions, higher than Black people.
Do they? Can I shout "scary Black man" on the street and have the forces of fascism ride to my rescue?
No, I don't think they can.
So a lotta trans people are in fact white, but trans people are explicitly NOT welcome in this white supremacist society.
Your praxis, is bullshit. Yes some trans femmes suck; no, it's not white supremacy.
